1 Glaim. 1

My invention relates to improvements: in brushes and is directed more particularly to the provision of a new and novel construction in brushes.

It isthe principal object of my: invention to provide a novel and. improved brush of the type in which elongated: bristles: are doubled longitudinally of themselves so that they are held.- in closed and: operating relationship in a unique manner so as to avoid: the separation of the bristleswhen same are asso atedwith the: com pleted product.

It. is another object of my invention to provide a device of the above described character which is relatively simple and compact "accordance with certain well known requirements and demands in this highly competitive industry and which is not only attractive in its appearance and practical in its value but also reliable in its operation.

With the foregoing and various other novel features and advantages and other objects of my invention as will become more apparent as the. description proceeds, the invention consists in certain novel features of construction and in the. combination and arrangement of parts aswill be hereinafter more particularly pointed out'in the claim hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:

Fig. 1 is a plan view of a portion of a strip of the bristle construction of the device of my invention.

Fig. 2 is a plan view of a portion of a strip of the bristle construction shown in a doubled over position.

Fig. 3 is a bottom plan view of the handle member used in the device of my invention, and

Fig. 4 is a side elevational view of the device of my invention with certain parts or portions thereof broken away or removed for purposes of clarity.

Referring now to the drawings more in detail in which similar characters of reference indicate corresponding parts in all views, my invention will be fully described.

The brush is made up of strands or bristles 2 of any appropriate material such as animal or vegetable filaments which are cleaned or combed and are cut into equal elongated lengths.

The dimensions of the strands are of course determined by the requirements of the ultimate brush body and it will be understood that any desired length of strand may be employed.

The strands are first laid loosely in a thin 2. layer upon a base or horizontal, support in juxtaposition with respect to each other and; with the strands arranged parallel to. each other sub stantially as shown in Fig. 1. It will be understood of course that. the thickness of this layer may be varied to suit the individual requirements of the type of brush being produced.

The strands 2 are placedover a primary hinder or supporting tape member 4 which is preferably a thin, narrow strip of ajflexible or bendable inat-erial such as paper fabric, Celluloid; or the like. The bristles: orstrands 2. are arranged transversely of the supportingtape member 4' at points intermediate their ends. That is; to say the bristles are arranged on the tape so that, they extend outwardly from both sides. thereof and, if desired they may be secured to the tape in some suitable manner as by an adhesive'material such as collodion which maybe. applied either to the tape or bristles, or both.

The bristles may be the well known hair bristles or they may be of; some suitable synthetic material but will oftcourse in all-cases be of such a nature as will. give in a: finished brush the desired brushing or scrubbing action. Prefer-ably the bristles usedwillbe of a fibrous material, that is, natural vegetable fibers; These are well adapted for the. practice of. my invention because they are relatively porous and furthermore, are inexpensive.

The supporting tapelmembers. above described may take various forms and they may be of: various materials-while the bristles may be coated or laid thereon in various ways and held, thereon by various means. The tape with the bristles is in effect a supporting tape which is coated with bristles extending outwardly therefrom in opposite directions.

A secondary tape member 6 of similar dimension and material to the member 4 is then placed directly over the midsection of the strand 2 and the tape 4 substantially as is shown in Fig. 2.

While the strands are thus held between the tapes, a stitching operation is performed Whereby the tapes 4 and 6 are sewed to each other by a thread or threads 8 as shown in Fig. l. The stitching is placed lengthwise of the parallel tapes and preferably along the longitudinal midsections thereof.

Obviously this stitching operation is not sufficient to hold the strands in absolutely secure relation with the tapes inasmuch as the stitching normally circumvents the individual strands. Nevertheless, a relatively tight fitting closure results.

if desired, the inside surfaces of the tapes may be gummed so as to be moistened upon assembly thereof whereby the moistened tapes may be caused to adhere to the opposite surfaces of the strands so as to hold the same in more rigid relationship.

The bristles 2 are doubled longitudinally of themselves and the opposing tapes 4 and 6 are doubled transversely of themselves so as to produce a double thickness of bristles and of tapes as shown substantially in Fig, 2.

Stitching together of the opposite sides of the doubled over pair of tapes 4 and 6 enclosing the doubled over bristles 2 is accomplished so as to produce a brush body member.

The stitching may consist of a thread or threads 10 and same succeeds in holding together into a unitary construction a brush body member comprising a plurality of doubled over strands, a folded primary tape member overlying the same and a folded secondary tape member secured between the folds of the strands, all being tightly and firmly secured together by means of stitching. The strands being doubled and embraced between the tapes are not easily removable individually or in groups.

A handle member generally indicated by 12 is provided and consists of a top portion 14 which may be manually grasped for operational use. The handle member is preferably made of wood or of a similar material.

A lower portion I6 is inset from the top portion on all sides substantially as shown in Figs. 3 and 4, is adapted to receive the brush body member, and is of such construction that the taped portion thereof may be secured thereto by means of nails, rivets, screws or the like. The brush body member may be of such length as to enclose completely the portion IE or it may be made of such length as to enclose only apart of the lower portion 16.

If desired, several body members may be employed, one being disposed over another upon the handle member so as to provide a thicker brush for special purposes.

The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claim rather than by the foregoing description, and all'modifications andvariations as fall within the meaning bristle structure supporting portion depending from the underside thereof, said supporting portion being of relatively less longitudinal length and transverse width than said body member and forming with the underside thereof a continuous horizontal ledge extending outwardly from the upper side of the supporting portion to outer vertical longitudinal side and transverse end edges of the body member, a bristle structure extending around the longitudinal sides and transverse ends of said supporting portion and secured thereto with an upper edge portion thereof below and against said ledge and spaced inwardly of the longitudinal side and end edges of the said body membensaid bristle structure including an elongated strip of flexible bristle supporting material doubled upon itself longitudinally forming double plies and bristles-doubled upon themselves between and secured to said plies and having outer 'free end portions extending transversely from said strip and downwardly from said supporting portion.
